/group/fetchAllGroups/returns groups without subject and creation; findGroupInfos only fixes some

Welcome!

What did you do?

When fetching groups with GET /group/fetchAllGroups/{INSTANCE_NAME}, the API returns a list containing some groups without the subject key and without creation (or creation = null). Attempting to “repair” these entries by calling findGroupInfos (get_group(id)) only succeeds for a subset of affected groups; others remain without subject/creation even though the group exists.

Code:

@router.get("/")
async def get_groups() -> list[dict]:
    try:
        url = f"{BASE_URL}/group/fetchAllGroups/{INSTANCE_NAME}"
        query = {"getParticipants": "false"}
        response = requests.get(url, headers=EVOLUTION_API_HEADERS, params=query)
        response.raise_for_status()
        data = response.json()
        print("Quantity of groups:", len(data))

        if not isinstance(data, list):
            print(f"Unexpected response format: {data}")
            raise HTTPException(
                status_code=500, detail="Invalid response format from API"
            )
        
        # Temporary handling of groups without subject
        data_with_subject = [group for group in data if group.get("subject")]
        print("Quantity of groups with subject:", len(data_with_subject))
        data_without_subject = [group for group in data if not group.get("subject")]
        print("Quantity of groups without subject:", len(data_without_subject))
        if data_without_subject:
            for group in data_without_subject:
                try:
                    updated_group = await get_group(group.get("id"))
                    if updated_group.get("subject"):
                        data_with_subject.append(updated_group)
                        print(f"Group {group.get('id')} updated successfully")
                except Exception as e:
                    print(f"Error updating group {group.get('id')}: {str(e)}")
                    continue
        print("Quantity of groups with subject after update:", len(data_with_subject))
        
        return data_with_subject
    except requests.RequestException as e:
        print(f"Error fetching groups: {str(e)}")
        raise HTTPException(status_code=500, detail=f"Error fetching groups: {str(e)}")
    except Exception as e:
        print(f"Unexpected error: {str(e)}")
        raise HTTPException(status_code=500, detail=f"Unexpected error: {str(e)}")

What did you expect?

fetchAllGroups returns consistent objects for every group with at least:

{
  "id": "1203...@g.us",
  "subject": "Group name",
  "creation": 1719230845,   
  ...
}

findGroupInfos returns a group given its id exists.

What did you observe instead of what you expected?

fetchAllGroups includes entries where subject is missing and/or creation is null.

For some of those same ids, findGroupInfos returns 404 Not Found.

Representative log:

Error fetching group: 404 Client Error: Not Found for url:
http://localhost:8080/group/findGroupInfos/teachy?groupJid=xxxxxxxxxxxxxxxxxx%40g.us&getParticipants=False

Error updating group xxxxxxxxxx@g.us: 500: Error fetching group: 404 ...

The group does appear in fetchAllGroups, but cannot be fetched by findGroupInfos using its id.
